Definitions

  • the present specification relates to aquaculture shrimps and applied products utilizing the same as well as a method used in the aquaculturing the shrimps.
  • Carotenoids are either obtained directly from feed or metabolically converted from other carotenoids contained in feed.
  • feed used in the culturing of shrimps is supplemented with carotenoids such as astaxanthin (for example, Patent Documents 1 and 2).
  • the present specification aims to provide aquaculture shrimps with good appearance.
  • an aquaculture shrimp with good appearance is provided.
  • the present specification relates to an aquaculture shrimp containing carotenoids, whose second antenna is not broken.
  • “Shrimps” that serve as the subject of the present specification includes, without being limited to its size, a so-called lobster, prawn, and shrimp in the classification of foods.
  • Shrimps that serve as the subject of the present specification are academically classified under the order of Decapoda, superfamily of Penaeoidea.
  • the family Penaeidae is included.
  • Organisms of the family Penaeidae include shrimps belonging to the genus of Farfantepenaeus, Fenneropenaeus, Litopenaeus, Marsupenaeus, Melicertus, Metapenaeopsis, Metapenaeus, Penaeus, Trachypenaeus, Xiphopenaeus, for example.
  • edible shrimps include kuruma shrimp (Marsupenaeus japonicus), minami kuruma shrimp (Melicertus canaliculatus), black tiger (Penaeus monodon), chinese white shrimp (Penaeus chinensis), green tiger shrimp (Penaeus semisulcatus), western king shrimp (Penaeus latisulcatus), indian shrimp (Fenneropenaeus indicus), sand shrimp (Metapenaeus ensis), middle shrimp (Metapenaeus intermedius), Penaeus occidentalis, blue shrimp (Penaeus stylirostris), red tail shrimp (Penaeus pencicillatus), whiteleg shrimp (Litopenaeus vannamei), for example; however, they are not limited thereto.
  • whiteleg shrimp (Litopenaeus vannamei) that belongs to the genus Litopenaeus in the family Penaeidae is one of the subjects in the present specification.
  • nektonic species include nektonic species and non-nektonic species.
  • nektonic species can be used in a water tank in three dimensions, they are suitable in production at an overcrowded state. Either species may be used in the present specification; however, at an overcrowded state, contact frequency increases and the possibility of having a defect in the second antenna is higher, and thus, the nektonic species may be used.
  • nektonic species include sakura shrimp (Lucensosergia lucens), pacific pink shrimp (Pandalus eous), chinese white shrimp (Penaeus chinensis), sand shrimp (Metapenaeus ensis), and whiteleg shrimp (Litopenaeus vannamei).
  • Aquaculture shrimps refer to an aquacultured shrimp, and any shrimp aquacultured in either fresh water or sea water (including artificial sea water) is included.
  • Shrimps contained in a system where artificial conditions are imposed are included. Such system allows the farming of this group of crustacean in a suitable embodiment, which can control the growing and harvesting of shrimps to be provided for use, processing, and/or sale.
  • Carotenoids refers to yellow to red, or purple insoluble polyene pigments that are produced by green plant and certain kinds of fungi, yeast, mushrooms, bacteria, and the like. “Carotenoids” include any molecules that are classified into yellow to red pigments such as carotenes and xanthophylls. Of these, astaxanthin, in particular, artificially synthesized artificial astaxanthin is one of the carotenoids that is the subject of the present specification. Details of synthetic astaxanthin are provided herein below.
  • an aquaculture shrimp contains carotenoids greater than or equal to 0.1%, greater than or equal to 0.3%, greater than or equal to 0.5%, greater than or equal to 0.8%, and greater than or equal to 1%.
  • “Second antenna” refers to an antenna that is commonly referred to as the mustache (refer to FIG. 1 ). "The second antenna is not broken” refers to that the second antenna has no damage. In such case, the two antennas on the left and right are approximately of the same length.
  • the aquaculture shrimp of the present specification includes cases where the length of the second antenna is longer than the body length. When this second antenna is defective, the product value is reduced. Moreover, when the second antenna is defective, it would affect the health condition of the shrimp. Generally, as the second antenna is longer than or equal to the body length without a damage, in the present specification, an individual having a second antenna with a length less than or equal to the body length is considered to have a damage in the second antenna. The second antenna is measured from the root of the antenna using a ruler.
